GAS-LIGHTING DEVICE.

Specification of Letters Patent.

Patented Dec. 3, 1912.

Application tiled July 18, 1912. Serial No. 710,157.

To all whom it may concern:

Be it known that I, THOMAS S. NEWMAN, a citizen of the United States, residing at Newton, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Gras-Lightingr Devices, of which the following is a specification.

This invention relates to improvements in gas lighting devices and particularly to those devices designed to li rht a plurality of jets by means of a lightedtorch connected with a gas supply.

This invention is especially adapted to be used in connection with an ordinai'y gas stove having a plurality of burners on or near its upper surface.

The device of this invention can be easily built into gas stoves when the saine are being constructed and it has the further advantage of heilig very easily attached to a great many types of gas stoves already in actual use.

My invention has for its object the provisions of a simple and effective appliance for quickly and safely lighting a plurality of burners of a gas stove,said appliance being not only effective hutfclieap, both in regard to its initial cost and the after expense of operation.

Another object of my invention is to provide a device of the character indicated in which all of the. working parts are exposed to view and manipulation so that the saine can be easily kept in repair or replaced if hrokenwthe same idea as prevails in the modern open plumbing.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims.

Referring to the drawings Figure 1 is a plan view of an ordinary gas stove with my gas lighting device attached thereto, showing a portion of the top of the stove broken away. Fig. 2 is a side elevation of the device. Fig. 3 is a detail cross section of a portion of my device illustrating a portion of the supply pipe, torch and the pipe connecting said supply pipe and said torch.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings 4 is a gas stove provided with burners or jets 5, 6, 7 and 8. These burners are supplied with as from the main supply pipe 9 which is ocated along the front top edge of the stove. The supply pipe 10 on my device is connected with the main supply pipe 9 and pro]ects inwardly therefrom. Fixed to the supply pipe 10 are the brackets 11 and 12. Rotatably mounted in said brackets 11 and 12 is an operating rod 13 which is provided at its outer end with a handle 14 and at its inner end with a gear 15. At the inner end` of the supply pipe 10 is an upwardly projecting elbow 16. Fixed to and connected with this elbow is a connecting pipe 17. Rotatably mounted on and connected with the connecting pipe 17 is a torch 18 which has an upwardly projecting portion 19 and a horizontally projectingT portion 20. The bore 21 of the connecting pipe 17 is much smaller in diameter than the bore 22 of the supply pipe 10 or the bore 23 of the torch 18. Fixed to the upwardly projecting portion 19 of the torch 18 is a gear 24 adapted to mesh with the gear 15 of the operating rod 18.

The method of application of my device to a gas stove and the operation thereof is as follows: The main supply pipe 9 of a. gas stove is tapped and a T 2G inserted at about. its cent-ral portion. The screw-tlireadcd end 25 of the supply pipe 10 is screwed into this T. The Supply pipe l0 is then connected by this means with the main supply pipe of the stove and in such a iiiannei' that my entire device is located beneath the top grating 27 of the stove t so that the end 20 of the torch 18 will swing over the burners 5, (i, 7 and 8 of the stove and under said .top grating. Being attached in this manner the entire device is out of the way. The handle 14 projects a slight distance beyond the front edge of said stove and is in such a position that it can be easily operated. The end 20 of the torch 18 is kept constantly lighted. At this point I wish to call particular attention to the bore 21 of the connecting pipe 17 which is made very small in diameter, much smaller in fact than either the bore 22 of the supply pipe 10 or the bore 23 of the torch 18. The bore 22 of the supply pipe 10 may be ol any suitable diameter, even as large as the diameter of the bore of the main supply pipe 9. The bore 23 of the torch 18 is preferably of a smaller diameter than that of the main supply pipe 9 but is considerably larger than the bore 21 of the connecting pipe 17. Because of this construction it is possible to allow the gas to come full pressure at all times through the supply pipe 10. Owing to the very small diameter of the bore 2l only a small amount of gas can pass therethrough. This expands in the comparatively larger bore Q3 of the torch 18 and at its outer end burns in the form of a medium size or small flame and without any blowing" or pressure, thus it is possible to use a very small amount. of gas and yet keep the device constantly lighted. It has been found in experimenting that the amount of gas used is extremely slight..

In operation when it is desired to light one or more of the burners 5, (i, 7 and 8 of the stove 4 the torch 18 is revolved in the path indicated by the dot and dash circle A in Fig. l by turning the handle 14 until it comes over the bui-ner which it is desired to light.. rl`lie coc-lt of such burner is opened and the burner instantly lights. Any number of burners can be successively lighted in the same manner.

This invention is particularly valuable in eiiiployinents where a gas stove is con st-antly used aiid where the different burners are being` constantly extinguished and religlited, such for instance as in candy factories. In this and other cases it is much more advantageous to use my appliance than to constantly waste matches and more particularly wastc thetime of employees 1n procuring and' lighting the matches and thus the burners.

It has the further advanta e of making the use of a gas stove more sulla for the reason that there can be no such explosions as sometimes occux` when the gas is turned on and then a match cannot be found and lighted for several seconds; furthermore, it obviates the necessity of havini a large su ly of matches constantly on and.

llllhving thus described my invention what I claim and desire to secure by Letters Patent is:

1. A gas lighting device comprising in combination a horizontally disposed supply pipe, a vertically disposed pipe connected therewith, a torch comprising a horizontal portion and a vertical portion, the vertical portion being connected with and rotatably mounted on said coiinectin pipe and the bore of said connecting pipe being smaller in diameter than the bore of either said supply pipe or said torch, and means to rotate said torch.

2. A gas lighting device comprising in l combination a horizontally disposed supply pipe, a torch comprising a vertically disposed portion and a horizontally disposed portion, the vertically disposed portion being connected with and mounted on said supply pipe, a plurality of brackets fixed to sai supp y pipe, an operating rod rotatably mounted in said brackets and means to conneet said o erating rod with said torch whereby sai( torch may be revolved.

3. A gas lighting device comprising iii combination a horizontally disposed supply pipe, a vertically disposed pipe connected therewith, a torch comprising a horizontal portion and a vertical portion, the vertical portion being connected with and rotatably mounted on said connecting pipe, and means` to rotate said torch.

4. A gas lighting device comprising in combination a horizontally disposed supply pipe, a vertically disposed pipe connected therewith, a torch comprising a horizontal portion and a vertical portion, the vertical portion being connected with and rotatably mounted on said connecting pipe, the bore of said connecting pipe being smaller in diameter than the bore of either said su )ply )ipc or said torch, a gear fixed to said torcli, a plurality of brackets fixed to said suplply pipe, an operating rod rotatably niountet in said brackets, and a gear fixe to said operating rod and adapted to mesh with said gear fixed to said torch, whereby said torch may be rotated.

. 5. In a gas range provided with a main supply pipe a gas lighting device comprising in combination a horizontally disposed supply pipe directly connected with said main supp y pipe, a vertically disposed pipe connecte with said last mentioned pipe, a torch comprising a horizontal portion and a vertical portion, the vertical portion being connected with and rotatably mounted on said connecting )ipe and the bore of said connectin pipe eing smaller in diameter than the gore of either said supply pipe or said torch and means to rotate sai torch.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
